Historian Brenda E. Stevenson (pictured in her UCLA office, with an African sculpture) mostly writes about the long-gone — 18th and 19th century African Americans, and the lives of enslaved women. Then came the case that made history while L.A. watched: Korean-born shopkeeper Soon Ja Du killed black teenager Latasha Harlins over a bottle of orange juice. A jury convicted Du of voluntary manslaughter, but she was sentenced only to probation and community service.

Stevenson's new book, "The Contested Murder of Latasha Harlins," analyzes the other "no justice, no peace" case that echoes through the 1992 riots and into the present day.

Thirteen days after the Rodney King beating, Harlins was shot and killed. Where were you when all of this happened?

I had just moved to Los Angeles. I'd been teaching at the University of Texas at Austin, and I thought, "L.A. is going to be this wonderful, liberal place." The Rodney King event happened, then Latasha Harlins. I thought I'd jumped from the frying pan into the fire.

You have the [shooters'] assumption of a deadly threat. Soon Ja Du testified that she thought Latasha Harlins had a gun in her backpack; that's why she came out with the gun herself. George Zimmerman said, "I thought he was going to kill me."

The defense attorneys used almost the same terms in describing Latasha Harlins and Trayvon Martin. Latasha Harlins was not a gang member, she did not have a weapon in her bag, she did have the money [to pay for the juice] in her hand. Trayvon Martin did not have a weapon, he had iced tea and Skittles. I think it's similar, and the community has responded with a sense of injustice in both cases.

And women are very important — all six jurors [in the Martin case], the judge, his friend who was on the phone. [In the Harlins case], the defendant, the victim, the judge, the prosecutor. Women play important roles in the cases as well as the way the larger society has looked at the cases.

We've seen both L.A. crimes on videotape, but hasn't King's case eclipsed Harlins' in historical memory?

Not on the street and in the community, I don't think. But [the King case] was about men. The typical racialized dynamic is the black male and the white aggressor — this was the notorious LAPD being racist again. We saw it in Trayvon Martin.

People were not used to thinking about women in this way. The president just [spoke] about racial profiling — he never mentioned females once. Of course, he was talking about his experience, but he has two daughters.

When people [in the black community here] talk to me about the L.A. riots, they say it's about Rodney King but also about Latasha Harlins. At Eso Won bookstore last year, I asked the owner: "Do you have the new Rodney King book?" and he said, "Yes, but as far as I'm concerned, the riots were more about Latasha Harlins than Rodney King." He said: "She shoots a girl in the back of the head, the jury finds her guilty and she walks free."

Latasha Harlins did not survive the gunshot. At least Rodney King was alive. He could tell his story. But a 15-year-old girl had been killed. Latasha Harlins' name is part of South Central lore. Tupac Shakur has three songs in which her name is mentioned.

People will grab my arm and say, "Do you remember Baby?" They always make the comparison. This man was sentenced [to a month in jail] for beating his dog [Baby]. People are disgusted by the notion that someone would go to jail for hurting an animal but not a person.

Your book looks at the dynamic among the three women in the Harlins case: judge, victim and defendant.

If you look at the histories of the three — Jewish, African American and Asian American — at some point their families would have crossed paths in terms of their [economic, immigrant] experiences. But it's clear in Judge Joyce Karlin's sentencing that her experiences resonated not with Latasha Harlins and her family. Her family had been shopkeepers too, [like Du].

Young female African Americans in working poor families are often regarded just as young black males — as violent, as not being able to contribute to society. Soon Ja Du testified she thought Latasha Harlins was in a gang because her son had explained that gang members wore the kind of clothes Latasha Harlins had on. And [Du] said: "She hit me with that iron fist. I thought, 'She's going to kill me.'"

Judge Karlin's sentencing statement [spoke of] Du as being a good mother, being a good wife, that's why she was in the store that day. She believed that Soon Ja Du was the victim, this feminized victim.

Latasha Harlins' gender sort of disappears. Her class and race really did paint the portrait of a violent South Central youth attacking an older, small, fragile woman.

Did you talk to Joyce Karlin or Soon Ja Du or the prosecutor, Roxane Carvajal?

I spoke with Carvajal on the phone several times, but she refused to give an interview. Judge Karlin — we tried to get an interview with her and could not. Soon Ja Du said she would give an interview, then someone in her family picked up the phone and said she would not.

If you could interview them now, what would you ask?

I would ask Karlin: "What did you think the community or society would think of not giving Du any jail time? Did you have a clue it would affect your career as much as it did?" [Karlin was the subject of a failed recall. Her sentence was upheld becase of judges' broad sentencing discretion.] At some level [the sentence] had to be inexperience. [It was Karlin's first jury trial.]

I would ask Soon Ja Du, wasn't she really just very angry? Given the hardship of her family, her not wanting to own the stores, her being uncomfortable around the clientele, feeling her son had been victimized by gang members — I felt she approached Latasha Harlins with a great deal of anger. It's like, "I'm not taking anything else off these people."

What do you want people to take away from your book?

I want people to think more about women and their role, particularly in the criminal justice system — women as victims but also as perpetrators and as lawyers, judges, juries. I want people to think about the black female and her troubled place in the justice system as well.

Did working on the book change you?

It did. I never thought of myself as doing anything outside the 19th century. It really pulled me into Western history, into looking at women from other ethnic and racial groups. It got me really interested in the court system.

I'm very careful about my daughter, where she goes, what she wears, the size of the purse she takes. Whenever she goes into a store, I insist that she take a tiny purse or I will hold her purse for her if we are together because I don't want her to be accused of shoplifting. She knows I'm overprotective in this way, but it happens too often. My daughter sometimes says, "This is really unfair," and I say, "Yes, it is unfair, but stay safe first."

First Rodney King, then Latasha Harlins. UCLA historian Brenda E. Stevenson, in the "Patt Morrison Asks" column, talks about her new book, "The Contested Murder of Latasha Harlins," the case that also undergirds the 1992 riots.

Critics were quick to call President Obama a “race-baiter” after he addressed the nation Friday about Trayvon Martin’s killing and what it’s like for young black males in this country who, he said, “are painted with a broad brush.”
